DANVTLLE, ILLINOIS PROCESS OF FORMING COMPOSITE HELS Application inegi February 15,1990.. serial in. 428,711. f

This invention relates to improvements in the process of forming composite rubber heels.

The primary object of this invention, is to provide means for fastening a rubber wearin heel to the upper lift of a shoe which is a apted to firmly connect both of the above parts and which will not be affected by atmospheric conditions.

A still further object of this invention is to rovide a novel form of fastener for fastening a. rubber heel to a shoe upper lift whereby as the rubber heel becomes worn, the connecting means being of a similar material, will wear accordingly and ktherefore prevent the marring of floors of a highly varnished nature.

A still further Object of this invention is to provide a strip of resilient material for being fastened through openings corresponding in the rubber heel and shoe upper lift which, when the rubber insert is placed in position therein, and out of at both ends flush with the surface of the leather heel lift and the rubber heel lift, a certain amount of expansion will Occur thereby forcing the strip into tighter engagement with the associated part of the heel and prevent the rubber heel from being displaced after the same has been laced on a shoe upper.

Hereto ore, it has been common practice 'to connect rubber heels, to a heel lift by means of pegs formed of metal or small screws. Such practice is objectionable because the heel subjected to the friction of pavements soon causes the rubber heel to be worn down to the metal pegs or screws whereby the same are exposed and usually come in contact with highly polished floors and mar the same.

The above disadvantages are overcome b joining the rubber heel and shoe upper li by a flexible member having resilient qualities and in the better class of shoes it is proposed to associate the leather heel lift with 'the rubber heel by means of colored pegs formed of a similar material to the rubber heel. f

Other Objects and advantages of the in vention will become apparent during the character A will course of the following description, forming 'heel secured thereto Aby pegs prior to the insertion of the resilient connecting means;

Figure 4 is a cross-sectional view of the heel hft and the rubber heel showing the same connected by the rubber pegs and the wooden retaining pegs removed therefrom;

Figure is a longitudinal elevational view of a resihent insert adapted to be passed through/the openings in the heel lift of a rubber heel for connectin the parts;

Figure 6 is a side elevational view showin the connecting peg clamped through the hee lift and the rubber and the method of glueing the rubber inserts at an area adapted to be passed into the Openings of the heel lift and rubber heel; and

Figure 7 is asimilar view showing the rubber` insert being passed through the openings in the heel lift and rubber heel and the adhesive area of the rubber insert presented to the Opening prior to the cuttin olf of the insert flushed with the surface o the rubber heel. I

For a consideration of a, more detailed description of the invention, attention is directed to the drawing wherein the reference generally be employed to designate a heel li t formed of leather as is the usual common practice. Heretofore, the rubber heelB has been secured to the heel lift A by means of counter-sunk metallic pegs or screws whereby the heel B is associated with the heel lift A as Well as being attached to the shoe upper. The present form of inopenings 5 and 6 are in alignment, wooden pegs 7 may be driven thereinto in order to hold the heel lift A and the rubber heel B in position.

After the rubber heel B and shoe lift A have been associated together, a rubber strip 8 having a tapered and pointed end 9 is inserted in the corresponding openings 5 and 6 as illustrated more clearly in Figures 4 and 7. The resilient or rubber strip 8 is formed of a larger diameter than the corresponding openings 5 and 6.of the shoe lift and rubber heel so that as illustrated in Figure 4, when the rubber strip 8 is passed through the opening'it will be reduced or squeezed together as at l0 when being drawn through an opening and as also illustrated in Figure 5, the upper portion of the rubber strip 8 is supplied with a coating of adhesive 1l by a suitable applicator. The adhesive 11 having been applied to the strip 8, the strip is then drawn through the openings 5 and 6 until the adhesive portion 11 isreceived in the opening and the pullingtension on the rubber strip Sis then relieved, whereby the rubber strip 8 is caused to expand in the openin s 5 and 6 to a certain degree as illustrated in igure 7. It is to be understood when the rubber strip 8 is being passed through the openings 5 and 6 of the heel lift A and rubber heel B, that the same is elongated which reduces the diameter of the strip and allows the same to be passed through the openings 5 and 6. At this juncture, the rubber strip 8 is drawn through the openings until the upper end of the strip 1s flush with the leather heel lift A and'then the strip 8 may be severed from the connected heel lift A and rubber heel B at a point flush with 4the surface of the rubber heel B.

The above operation is performed with the rubber strip 8 through each of the series of openings 5 and 6 until all ofthe openings have been filled with the rubber inserts and heel strip A and rubber heel B have been permanently secured together.

It is to be understood that the rubber securin strip 8 may be circular, square or rectangu ar in cross-section and that .the same may be pointed at one end or provlded w1th a suitable threading device so that the same may be threaded through the openings 5 and 6 with the least possible amount of dificulty.

After the leather heel lift A and rubber heel B have been associated as above described, the same are secured to the shoe upper heel section by passing metal pegs 12 as shown in Figure 3 through counter-sunk ortions in the heel B and through the li t A until the metal pegs are flush with the heel lift A whereby the egs are received in the heel portion of the s oe upper. This operation may be reversed by assing the metal pegs through the heel portion of the shoe u per first in order that the same may enter t e shoe heel lift A until the same reach a point at the juncture between the leather lift A and the rubber heel B.

Having thus described my invention, what is claime is 1. The process of connecting a leather heel lift to a rubber heel consisting of passing a rubber strip through the same, applying adhesive to the rubber strip, and finally cutting off the rubber strip at a point adjacent the surface of the rubber heel.

2. The process of connecting shoe parts, consisting of passing a rubber strip through openings therein, applyin adhesive to a portion of the rubber strip, acpted to be entered into the openings of the heel part, and finall severing the rubber strip at a juncture ilus with the heel part.

3. The process of associating a rubber heel with a leather heel lift consisting of forming openings therein, passing or threading a strip of material similar to the material used for the heel portion, placing adhesive on one end of the strip, placing tension on the rubber strip while drawing the same through the openings in the heel lift and heel whereby the strip will be elongated and reduced in diameter until the strip has passed through the openings to the end thereof, and finally severing the strip from the heel by cutting the 1sltrilp at a point flush with the surface of the 4. The process of connecting heel sections comprising forming openings 1n the heel section in alignment with one another, threading a strip of rubber material through the openings, coating a portion of the rubber strip with an adhesive, drawin the strip through the openings until the a hesive portion is received in the openings, and finally severing the strip from the heel sections at a point flush with the surface of one of the heel sections.

5. A process of forming composite heels comprising forming openings in each of the heel sections aligning with each other, threading a rubber strip through the openings, placing adhesive upon the opposite end of the rubber strip, drawin the rubber strip through the openings o the heel sections until the adhesive. portion of the strip is received in the openings, and severing the rubber strip from the heel sections at a. point flush with the surface thereof.

In testimony whereof I aflix my signature.

JOHN JASUS.
